Absolute Line Intensities of the ν₆ Band of CH₃³⁵Cl at 10 μm

Strengths of individual lines in the ν degenerate fundamental at 10 μm of methyl chloride have been measured at room temperature using a diode laser spectrometer. From these measurements we have determined by a linearized fit two significant intensity parameters, namely, the band strength, S = 15.06 ± 0.19 cm atm at 297 K and the parameter α = 0.0081 ± 0.0017 of the Herman-Wallis factor F = (1 + αKΔK + ···).
